Specification forming part of Letters Patent No. 146,688, dated JanuaryO,1S74;application tiled June 13, 1873.

To all whom 'it may concern:

Be it known that I, PHILIP KLo'rz, of the city and county of Baltimoreand State of Maryland, have invented certain new and useful Improvementsin Firellace Heaters 5 and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawings forming part of this speciiication, in which-Figure l is a perspective view, a portion of the upper part of the stovehaving been broken away to reveal the construction more plainly. Fig. 2is a vertical transverse section; Fig. 3, a bottom-plan view of thestove. Fig. 4 is a perspective view of the inner cover or hood whichincloses the upper part of the magazine 5 Fig. 5, a horizontal sectionof the same, showing the. outer cover also in place, and the dividingpartitions that keep the products of combustionin front. Fig. 6 is aperspective view of the detachable plate for the name or the proprietorstrade-mark. Fig. 7 is a section through linevx m of Fig. 6, representingthe manner in which the naine-plate is secured to the stove. Fig. 8 is aperspective view of the upper surface oi' the entablature, the twocovers and the ring and damper having been removed. Fig. 9 is aperspective view of the ring and damper and Fig. 10 is a perspectiveView of the outer cover or top of the stove,

showing the door open.

Similar letters of reference in the accompanying drawings denote thesame parts.

The object of this invention is to increase the front radiation ofthestove, for the purpose of more thoroughly warming the lower apartmentsof the building in which it is placed. To these ends my inventionconsists in the several means employed for accomplishing the respectiveobjects above stated, substantially as I will now proceed to describe.

And, first, the means for increasing the front radiation of the stove.These consist, essentially, in av novel` and peculiar constructionwhereby the heated currents of air, gases, and other products ofcombustion from the rechamber are made to pass up in the front part ofthe stove, and thence around to the side pipes.

The stove is constructed with the ordinary base B, lire-chamber A,entablature E, side tlues C Cf, magazinel D, faceplate F, anddirect-draft ue G, capable of being closed by a damper, g, with a handleextending to the front. rlhe draft-chamber within the entab lature isdirected into a front compartment, H, and a rear compartment, H', bymeans of two septa or vertical partitions, h h,`one in front of the ueC, and the other behind the flue C. When the direct-draft damper g isclosed, the smoke and other volatile products of combustion passdirectly up into the front draft-chamber, and thence to the iiue C.Diving into this iiue, they pass to theI base B, where they proceed`around the rear side ot' the ash-box in the horizontal passage I, andrise, through the flue C, into the rear compartment H', and thenceescape to the smoke-Hue and the chimney; The top of the magazine iscovered by a cover or hood, J, (represented in` Fig. 4,) which is fittedupon or into the project (Shown in Fig. S.) This cover is provided withan oblique y ing upper end d of the magazine.

flange, i i, adapted to come in line with the partitions 7L h', andconnect them together, said partitions andan ge forming adividing-plate, A

which separates the front from the rear draft` space. Upon a collar orflange, e, projecting upward from the upper plate of the entabla- -ture,around the upper end of the magazine, I t a ring, L, the construction ofwhich is clearly shown in Fig. 9. rlhe ring is of greater diameter atits lower than at its upper edge. The lower edge tits upon the collar e,while the up per edge rests firmly again st the dan ge m around thelower edge of the opening M, and against the side iianges t' i, abovedescribed. The upper edge of the ring comes on a line with thehorizontal part of the door-ange m, and inside of the ring the anges t'i are enlarged, so as to completely ll the space between the enlargedpart ofthe ring and the wall of the cap J, and thereby prevent thesmoke, dto., from passing through the ring from the front space H tothe'rear space H. A collar, K,

cast upon the upper plate of the entablature,

forms a portion of the direct-draft ilue, and the height of this collaris so adjusted inthe manufacture that it will be covered by a projecting horizontal flange, l, formed on the rear edge ot the ring L, as shownin Figi, and more clearly in Fig. 9. The damper g is arranged upon theiange l, being properly pivoted or hinged thereto, and the handle ofthel damper may be held and guided by a lug on the side of the ring, asclearly shown in said Fig. E). The cap J having been placed upon the topof the magazine, and thering L secured in position around it, With thedamper. g resting on the collar K, I next place around the projectingupper end of the cap J an outside cap or cover, N, the shape andconstruction of which are clearly shown in Fig. l0.

The lower edge of this outer cover or stovetop iits closely upon theupper edge of the ring L, and the cap or top its tightly against thedoor-liange m, and against the side and top flange i' A door, M, isattached to the outer cover or stove-top, and closes tightly upon theiiange m. The door is itself provided With a top iiange, m', which, whenthe door is closed, supplements the flange m, and prevents any upwarddraft through the magazine. The rear side of the top N projects over, soas to cover and inclose, the damper g, and is provided with an opening,upon which the smoke-pipe can be properly fitted.

By the construction above described, it willv be observed that thedraft-space H is continued from the chamber Within the entablature, upinside of the ring L, and the outer cap N, around all that portion ofthe inner cap J which lies in front of the iiange i, so that, when thedirect-draft damper is closed, the volatile products and residuums ofcombustion pass through the holes 0 0, directly up into said space, andcirculate over and around the Whole front portion of the stove-top,Where a large amount of heat is given off by them before they enter thediving-flue C. The

heat thus given oii", being on the front side of y the stove, isradiated directly into the lower compartments of the house, where itismost needed. The products of combustion7 after passing aroundthrough'the flues C I G', emerge into the rear draft-'space H', andthence into the space around and over the rear side of the pa-rt J,Where nearly all their remaining heat is radiated through t-he thinsheet metal into the hot airspace around the rear side of the stove,whence it passes either to the lower or upper compartments of the house,according' to the condition of the hot-air registers and dampers. y

Having thus described my invention, what I claim is 1. A lire-placebase-burning stove in which the products of combustion `circulate freely.around the front portion only of the stove before they enter thediving-fine C', substantially as described, for the purpose specified.

2. A iire-place base-burning stove having an entablature and side iiues,and a cylindrical top projecting above the entablature, said top beingconstructed with an outer and inner Wall, and having the space betweensaid Walls divided into a front and rear compartment,V

and being arranged, with relation to the other parts of the stove, sothat `the volatile products of combustion circulate freely throughthe'i'ront compartment, around and over the front part of the innerWall, before entering the diving-nue, and freely through the rearcompartment, 'around and over the back part of the inner Wall, afterthey complete the circuit of the indirect draft, substantially asdescribed, for the purpose specified.

3. In a fire-place base-burning stove, the combination of the inner capor top J, the ring L, and the jacket or outer top N, substantially asdescribed, for the purpose set forth.

PHILIP KLOTZ.
